From a quick first look, this may not be an easy problem to fix, as the site bundles the site’s functionality with a load of tracking scripts.

For now, the best solution is to add iheartradio.ca to your Exceptions list in the app. This will permanently unblock the site, so you don’t need to keep reloading without content blockers. However, please be aware this means Better isn’t protecting you from the trackers on this site!
